If you want you can rewrite the formula into slope intercept form so you don't get confused:
y=4x-2
Choice 1:
y=4x-2
y=4(-5)-2
y=-20-2
y=-22
y=4(0)-2
y=0-2
y=-2
y=4(3)-2
y=12-2
y=10
The best choice is the first one.
I hope this helped!
Because k is constant, we can find it by multiplying the x-coordinate by the y-coordinate. If y varies inversely as x and x = 5 when y = 2, the constant of variation is k = xy = 5(2) = 10.
Make a 4x4 table where rows are Alice, Bart, Pamela, and Robert, and where columns are the professions: Dentist, Laywer, Teacher and Writer.
Start crossing out possible pairing person-profession using the facts given. When a job is clearly assigned, you can cross it off for the rest of the people, for example, Pamela is a dentist so none of the rest are a dentist (because we are told they have all different jobs).
Eventually your table becomes filled.
Alice is a Lawyer
Bart is a Writer <<< so this is choice (B) for your answer
Pamela is a Dentist
Robert is a Teacher

Answer:
Step-by-step explanation:
Let the three numbers be x, y, z
So from the problem given we can get the equations as
:
x + y+z= 66
x=2y
z=1x/3
Now we will make equation 1 have only one variable using equation 2 and 3.
y=1x/2 since x=2y
Now using equations 1, 3 and 5 we will get
x+1x/2+1x/3=66
11x/6=66
x= 66*6/11
x= 36
y=x/2=36/2=18
z=x/3=36/3=12
Therefore:
x = 36
y=18
z=12
